4 Claims.

My invention relates to improvements to terrestrial globes and moreparticularly to a mounting therefor.

It is one of the objects of my invention to provide a terrestrial globe,and mounting therefor, which may be illuminated by means of anilluminating lamp which is inserted in the globe.

A further object of my invention is to provide a mounting for anilluminated globe which will permit the ready removal of the globe fromits mounting in order that the lamp may be inserted originally and inorder that the same may be renewed from time to time.

Another object of my invention is to provide a support for the meridianring of the globe.

For the purpose of disclosing my invention, I have illustrated certainembodiments thereof in the accompanying drawings in which:

Fig. 1 is a side elevation, partly in section, of a globe embodying myinvention;

Fig. 2 is a detail section of the top pivot for the globe;

Fig. 3 is an enlarged view, partly in section, of the bottom support forthe globe;

Fig. 4 is a side elevation of a modication of my invention, in which afull meridian ring is provided;

Fig. 5 is a detail section of a top pivot for the globe;

Fig. 6 is an enlarged detail section of the bottom support for theglobe;

Fig. '7 is a detail section of the pivot mounting of the globe support;and

Fig. 8 is a side elevation of a portion of the meridian ring at thepoint where the pivot mounting is made.

In the embodiment illustrated, in Figs. 1 to 3 inclusive, I provide abase l which may be formed of stamped sheet metal, if desired, and isprovided with a semi-cylindrical dome 2. Transversely extending throughthis dome is a slot adapted to receive the meridian ring 3 which at thepoint it enters the slot is provided with an enlarged boss-like portionA? provided with a screw-threaded stem 5 extending radially of the ring.In mounting the ring on the base, the ring is inserted in the slot inthe dome and rests on the end walls of the slot. The stem 5 projectsthrough a clamping plate 6 which clamps within the dome and is held inits clamped position by means of a thumb nut l. This arrangementprovides for an extremely simple mounting easily assembled anddisassembled, and maintains the meridian ring rigid in its uprightposition.

The globe 8 in the structure illustrated is preferably formed of glasshaving the map formed thereon by printing the map on suitablyconstructed paper segments which are cemented to the glass globe. Thepaper of the segments is suiiiciently thin to be translucent. At thebottom pole of the globe, I provide a suitable opening, suiciently largeto accommodate an ordinary sized electric lamp. The walls of thisopening are protected by a ring 9 which is inserted through the openingand is provided with an annular flange I overlying the surface of theglobe and cemented in position to maintain the ring in place.

At the top of the lglobe I provide the usual time disc l l and at thepole the globe is provided with an opening through which is adapted toextend a hollow rivet I2 which not only clamps the time disc in positionat the top of the globe but also provides a bearing opening for theglobe at the top.

At the bottom of the meridian ring 3 I provide an enlarged boss I3 onwhich is supported the bottom globe mount and the lamp and lamp socket.To this end I provide a supporting stud lll screw threaded at its upperend and adapted to receive an ordinary lamp socket l5, preferably of theso called candelabrum type. At the lower end of this stud I provide anannular flange I6. Mounted on this stud lll and resting on the iiange i6is a supporting disc ll carrying a guide sleeve E8 adapted to enter theopening at the bottom pole of the globe. This sleeve I8 is provided withan annular shoulder I8 over which the edge of the disc l1 is turned toform the disc and sleeve practically into a single unit and the upperedge of the sleeve i8 is rounded and inturned as at I9. The stud I4 isprovided with a dat eX- tension 20 which is tted into a slotl 2| in theboss I3 and is mounted on a pivot pin 22 eX- tending through the boss.This extension 20 at one edge is formed with a ilattened abutmentportion 23 which when the support as a whole is swung out on the pivotpin 22 will strike against the inner wall of the slot 2| and act as astop to prevent the swinging of the mounting beyond a predeterminedpoint.

At the top, the meridian ring 3 is provided with an enlarged boss 24through which is threaded a pivot pin 25 which enters the hollow pivotI2 and provides a top pivot support for the globe. In assembly, asuitable lamp is inserted in the lamp socket l5 which may be swungoutwardly on the pivot pin 22 a suiiicient distance away from themeridian ring 3 to permit the slipping of the globe over the lamp and onto the supporting disc I1. After the globe has been mounted on thesupporting disc I1, it may be swung back into position within themeridian ring 3 to the point where the top pivot pin 25 may be screweddown through its boss 24 until its unthreaded end 26 passes through thehollow rivet I2. This construction provides a pivot support for theglobe whereby the globe is pivotally supported at both poles andprovides a ready means for providing an illuminating lamp on theinterior of the globe. It is quite apparent that the lamp socket I maybe provided with the usual pull-chain switch so that the light in theglobe may be turned on and oiY and likewise with the usual conduit wireswhich, in this instance, are lead through the bottom or" the base I andout through the top of the dome 2 to be carried through a suitableopening in the disc I'I and connected to the lamp socket in the usualmanner.

In the structure illustrated in Figs. 4 to 8 inclusive, I have discloseda structure wherein the globe may be mounted in a full meridian ring. Inthis structure, the full meridian ring 21, for the globe, is mounted inthe base I in the same manner as is the half meridian ring 3 illustratedin Fig. 1. On this full meridian ring at the bottom of the polar axis ofthe globe, I provide a support quite similar to the support illustratedin Fig. 3, but so mounted as to permit the lamp socket and support to beswung transversely of the meridian ring 21. To this end, I provide asupporting block 28, slotted as at 29 to embrace the meridian ring 21.At its top edge this block 28 is transversely slotted as at 3l! toreceive the flattened stem 20 of the support similar to that supportillustrated` in Fig. 3. This flattened stem is curved as at 3l on itsunderface to allow for clearance when the stem is swung on a pivot pin32 extending through the block and the top edge of the block is curvedas at 33 for clearance purposes. The slotted portion 29 of the block tsover the meridian ring and in order to make a nice fit, the meridianring is cut out as at 34 to accommodate the block and when the block isplaced in position, the end walls of this cutout portion hide the pivotpin 32. The block is held in position on the meridian ring by means ofrivets passing through the block and the meridian ring. In addition tothe cutout portion 34 I provide a reduced cutout portion 35 whichaccommodates the ilat stem on the bottom of the supporting stud I4.

If desired, I may use the same top pivot stud construction as isillustrated in Fig. 2, or I may use the modified structure illustratedin Fig. 5. In this structure, the pivot pin 36 has formed at the topthereof a clamping plate 3'I which is adapted to abut against themeridian ring 21 and is provided with a screw 38 adapted to pass throughboth the plate 31 and the meridian ring, and receive a nut 39 on theopposite side.

In assembly, the support is swung laterally or transversely of themeridian ring 21 a sufficient distance to allow a globe to be mounted onthe bottom support. The support and globe may then be swung to aposition where the globe is within the ring 21. While the globe is inits outward position, the top pivot pin 36 is inserted in its pivot holeand when the globe is swung into its normal position, the plate 31 abutsagainst the meridian ring and the screw 38 is inserted in position toprovide a stationary top pivot.
